Overview
Brief Summary
The purpose of this observational study is to evaluate the performance and safety of endovascular treatment with stenting (Optimed Sinus Superflex 635 or Qualimed Pontos-pp) or balloon angioplasty (Cardionovum Legflow or Optimed Nylotrack .035 + .018) according to current practice. The goal of the study will be achieved by assessing binary restenosis with duplex ultrasound, peri- and postoperative complications, technical success, target lesion revascularization, amputation and clinical outcome.

Eligibility Criteria
Inclusion Criteria
- •Patient must sign the informed consent form prior to the index-procedure.
- •Patient is older than 18 years.
- •Patient is compliant with the requested follow-up visits at week 6 and month 12 and the treatment regime.
- •Patient suffers from mild to intermittent claudication (Rutherford 1-3) or critical limb ischemia (Rutherford 4-5).
- •Target lesion is an occlusion or diameter stenosis is ≥50% by visual estimate.
- •Target lesion is located in the common and external iliac artery, in the common and superficial femoral artery, popliteal artery and/or the below-the-knee (BTK) arteries (anterior tibial artery, posterior tibial artery or peroneal artery).
Exclusion Criteria
- •Patients with Rutherford 0 and
- •Patient is pregnant.
- •Patients with estimated Glomerular filtration rate (eGFR) \< 30 mL/min/1.73m
- •Patient has an acute thrombus or aneurysm in the target arteries.
- •Patient has a life expectancy of \<12 months.
- •Patient has a target lesion that cannot be crossed with a guidewire.
- •Patient suffers from acute limb ischemia defined as any sudden decrease in limb perfusion causing a potential threat to limb viability.
- •Patient has scheduled elective non-vascular procedures within 3 months after index-procedure. Vascular procedures are allowed within 3 months after the index-procedure if it is guaranteed that acetylic salicylic acid and clopidogrel intake is not interrupted.
- •Contraindication for anti-thrombotic therapy (coagulopathy, ...).
- •Patient has a known intolerance to anti-thrombotic medication or contrast agents.
Outcomes
Primary Outcomes
Binary restenosis
Time Frame: at 12 months follow-up
Binary restenosis defined as ≥ 50% re-obstruction of the target lesion will be assessed by duplex ultrasound (peak systolic ratio \>2.4)
Secondary Outcomes
- Device-related complications(up to 12 months follow-up)
- Secondary sustained clinical improvement(at 12 months follow-up)
- Mortality(up to 12 months follow-up)
- Immediate procedural outcome(during index-procedure)
- Clinical outcome(at 12 months follow-up)
- Target lesion revascularization (TLR)(up to 12 months follow-up)
- Primary sustained clinical improvement(at 12 months follow-up)
- Amputation(up to 12 months follow-up)
